IgG4-related disease (IgG4-RD) is characterized by a systemic involvement of tumor-like lesions with IgG4-positive plasmacytes. We experienced a case of IgG4-RD developed in a patient with bronchial asthma (BA) and chronic rhinosinusitis (CRS). A 55-yr-old female patient with BA and CRS complained of both eyes and neck swelling as well as a recurrent upper respiratory infection in recent 1 yr. The serum levels of IgG4, creatinine, and pancreatic enzymes were elevated. A biopsy of the submandibular gland showed an abundant infiltration of IgG4-positive plasmacytes. Her symptoms remarkably improved after the treatment of a systemic steroid that has been maintained without recurrence. We report a rare case of IgG4-RD developed in a patient with BA and CRS.

BACKGROUND: Organophosphate insecticides poisoning is one of the most common toxicologic emergencies in Korea. There have been few reports of organophosphate intoxication via parenteral route, although many reports on organophosphate intoxication by oral ingestion were present in the literature. This study aimed to validate the clinical characteristics of organophosphage intoxication according to the route of administration to the body. METHOD: Data were collected retrospectively by the review of the medical records from 49 patients with organophosphate intoxication. Severity of intoxication was classified by the Namba's Classification. Collected data were analysed and compared on the clinical features and laboratory findings between the patient intoxicated by inhalation or contact(parenteral group, n=23) and the other oral ingestion(enteral group, n=26). RESULTS: Severity class by clinical features was higher in enteral group than parenteral group. Severity class by serum cholinestetrase level was not positively correlated with severity class by clinical manifestations. Cholinesterase level tended to overestimate the severity of intoxication in parenteral group. Ventilator therapy and admission to intensive care unit were more frequently needed in enteral group than parenteral group in case that the severity class by clinical features was equal. CONCLUSION: In patients with organophosphate intoxication by parenteral route, serum cholinesterase level of the patient had disparity with clinical severity of intoxication. Considering this disparity, clinical severity should be considered as a more important indicator for treatment of organophosphate intoxication including atropinization, rather than serum cholinesterase level in patients intoxicated by parenteral route.

PURPOSE: Gastric adenocarcinoma is the most common malignant tumor in Korea and immunochemotherapy can be alternative method of the treatment for it. So we evaluated several immunologic markers, Major Histocomatibility (MHC) Antigen and Intercellular Adhesion Molecule (ICAM)-1 which play an important roles in cellular immune response of the host to the tumar cells, HLA-DR/DP antigens, one of the MHC class II which is expressed in various conditions, CD 68 antigen which are also important factor in immune response to the tumor cells. MATERIALS AND METHODS: We compared the expression of MHC class II (HLA-DR/DP) antigens, ICAM-1 and the number of tumor-infiltrating macrophages presenting CD68 antigen in formalin-fixed paraffin-embedded tissue sections of 95 gastric adenocarcinomas using immunohistochemistry. In addition to analyze the relationship between expression of these antigens in gastric adenocarcinoma, histolopathologic findings such as tumor invasion, regional lymph node metastasis and histologic differentiation are evaluated. RESULTS: The rate of HLA-DR/DP expression was 60% and strongly associated with tumor differentiation, invasion and regional lymph node metastasis. ICAM-1 was expressed in 15% and slightly increased in well-differentiated carcinoma. The lack of expression of ICAM-1 was observed in high invasive tumor (T 4). CD 68(+) macrophages counts were significantly increased in around the tumor cells, compared to normal epithelia. HLA-DR/DP expression and infiltrating CD 68(+) macrophage numbers were significantly associated (p<0.05), but there was no correlationship between ICAM-1 and CD 68(+) macrophage numbers. CONCLUSION: It was considered that enhanced expression of HLA-DR/DP antigens, ICAM-1 and CD68(+) macrophages in gastric adenocarcinomas may be an immunophenotypic deviation. HLA-DR/DP and CD68(+) macrophages infiltration showed correlationship with tumor invasion and regional lymph node metastasis, that they may be used as a prognostic factor of the tumor growth.

Krukenberg tumor of the primary breast carcinoma is rare and this is almost invasive lobular carcinoma. They are usually bilateral and frequent in premenopausal women. Diagnosis of symptomatic Krukenberg tumor is reported to be 1 or 2 year after the diagnosis of primary neoplasm. But sometimes it is discovered prior to the detection of the primary breast carcinoma. Unexpected ovarian micrometastasis was recognized after oophorectomy of normally appearing ovaries in breast cancer patients. Existence of Krukenberg tumor means advanced primary disease and possible metastasis to other organs, and have a poorer prognosis. We report a case of Krukenberg tumors occurred 3 years after the diagnosis of primary ductal type breast carcinoma.

Background: The On-X valve was recently introduced. It was the aim of this study to assess the safety and feasibility from the data derived from 28 patients who underwent aortic and/or mitral valve replacement with this prosthesis in National Medical Center. Material and Method: From May 1999 and May 2003, a series of 28 consecutive patients who had been implanted with 32 On-X prosthesis were reviewed. The operative procedure comprised of 12 MVR, 10 AVR and 6 DVR. The study followed the guidelines of AATS/STS. Mean follow-up was 27 months (total 64 patient-years).

PURPOSE: We aimed to determine characteristics of host, causative organisms, and antibiotic susceptibility of bacteria in pediatric patients with UTI living in metropolitan area of Korea. METHODS: Retrospective investigation was done for the causative organisms of UTI in 683 pediatric cases treated at Ajou University Hospital from 2012 to 2017. Patients were classified into Escherichia coli and non-E.coli group, where E.coli group was subdivided into ESBL(+) and ESBL(−) groups based on whether the bacteria could produce extended spectrum beta-lactamase (ESBL). Antibiotic susceptibility of the causative organism was also determined. RESULTS: A total of 683 UTIs occurred in 550 patients, of which 463 (67.8%) were first-time infection and 87 (32.2%) were recurrent ones (2–7 recurrences, 2.52 average), and 64.9% were male and 35.1% were female. The most common causative organism was E.coli (77.2%) and ESBL(+) E.coli was found in 126 cases. The susceptibility of E.coli to 3rd or 4th generation cephalosporin was relatively higher than that to ampicillin or amoxicillin/clavulanic acid. ESBL(+) E.coli showed higher resistance rate to 3rd or 4th generation cephalosporin than ESBL(−) E.coli . CONCLUSION: New treatment guideline should be considered due to the incidence of ESBL(+) E.coli increased up to one quarter of UTI cases.

BACKGROUND: Nationwide external quality assessment (EQA) of the fecal occult blood test (FOBT) in Korea was first introduced in 2007-2009. The EQA results were analyzed to assess the current status of FOBT and to plan the continuation of the EQA program. METHODS: The surveys included 40 hospitals in the preliminary survey conducted in 2007, 249 general hospitals in 2008, and 389 hospitals in 2009. In the surveys, the participating hospitals provided the results of the distributed materials and replies to the questionnaire on the FOBT test procedures and quality controls. RESULTS: In the surveys conducted between 2007 and 2009, a total of 650 institutes submitted 653 test system results; 3 institutes used 2 kinds of methods. All of the institutes used immunologic methods; 107 institutes (16.5%) used quantitative equipments and 546 institutes (84.0%) used qualitative kits. Most quantitative tests yielded consistent positive or negative results; however, their cut-off and measured values differed according to the equipments used. A low-level material tested in 2007 was negative in the quantitative methods but positive in some qualitative methods because of lower detection limits. The discordance rates among quantitative tests were 3.2% in 2007, 4.4% in 2008, and 0% in 2009 and the rates among qualitative tests were 13.8% in 2008 and 2.6% in 2009. Semi-solid EQA materials showed the ability to evaluate the overall test procedures with acceptable stability. CONCLUSIONS: In the first Korean FOBT EQA, commercially available EQA materials were proven to be stable. Continuation of the EQA program and further education of laboratory personnel are needed to reduce inconsistency in results. Further, the test kit, procedures, and result reports must be standardized.

A diffuse interstitial infiltrative pattern of lung metastasis in a patient with malignant melanoma is rare and can be confused with benign conditions such as pulmonary edema or drug-induced pneumonitis. We experienced a case of diffuse interstitial infiltrative lung metastasis in malignant melanoma in a 37-year-old man. This case was confirmed by a transbronchial lung biopsy. We herein describe the findings on CT and positron emission tomography scan.
